The purpose of the present invention is to improve the performance of impact energy absorption of side impact loads. When subjected to a side impact load (F), a left side frame (14) is crushed first, and following the crushing of the left side frame (14), bent portions (22) of cross members (16), which are bent into a crank shape, buckle in a Z-like shape. Through these deformations, excellent impact energy absorption performance is achieved. In particular, since the manner in which the left side frame (14) is crushed and the cross member (16) buckles is different, tuning the deformation strengths thereof would allow the impact energy to be efficiently absorbed in a relatively short deformation stroke. |
